遇到了同样的问题，我已经解决了，但我使用的是linux系统，不是windows！以下是针对 /etc/nftables.conf 配置的详细修改方案，以允许 LocalSend 的 53317 端口通信：

---

修改步骤（基于现有配置）

1. 编辑配置文件

   sudo vim /etc/nftables.conf
   

2. 在 chain input 部分添加以下规则（置于 ssh 规则之后）：

   tcp dport 53317 accept comment "allow LocalSend TCP"
   udp dport 53317 accept comment "allow LocalSend UDP"
   

   最终效果示例：

   chain input {
     type filter hook input priority filter
     policy drop
   
     ct state invalid drop comment "early drop of invalid connections"
     ct state {established, related} accept comment "allow tracked connections"
     iif lo accept comment "allow from loopback"
     ip protocol icmp accept comment "allow icmp"
     meta l4proto ipv6-icmp accept comment "allow icmp v6"
     tcp dport ssh accept comment "allow sshd"
     tcp dport 53317 accept comment "allow LocalSend TCP"   # 新增
     udp dport 53317 accept comment "allow LocalSend UDP"   # 新增
     pkttype host limit rate 5/second counter reject with icmpx type admin-prohibited
     counter
   }
   

   注：

   • 规则需放在 policy drop 之后、limit rate 之前。

3. 保存并测试配置

   sudo nft -f /etc/nftables.conf  # 加载新配置
   sudo nft list ruleset | grep "53317"  # 验证规则是否存在
